Abstract

Based on a mechanical connection channel project in Hangzhou, Aiming at the settlement problem of tunnel structure in the jacking process, the characteristics of connection channel structure design and mechanical construction are analyzed, and the elastic foundation beam theory is introduced. The initial end fixed cantilever multi-section foundation beam model is established, and the parameter sensitivity analysis and engineering case analysis are carried out. The results show that the end settlement increases with the increase of bending spring stiffness coefficient of tunnel structure, and the end settlement is hyperbolically related to the logarithmic stiffness coefficient. The subgrade coefficient and the end settlement showed a linear decreasing relationship; the end settlement increases with the increase of initial rotation angle; the endfixed multi-section foundation beam model has certain reliability in simulating the influence of grouting on the settlement deformation control of subway tie passage.
